Description

Technical Field

[0001] This invention relates to the field of flying car technology, and in particular to a flying car perception and control method and device based on an airborne privacy protection zone. Background Technology

[0002] With the development of urban air mobility (UAM), flying cars operating at low altitudes (typically 30–150 meters) will gradually become the norm. While their onboard high-definition cameras, lidar, and other sensors enable navigation and obstacle avoidance, they inevitably collect sensitive information such as ground-based buildings and human activity. Current technologies mostly employ fixed-sensing strategies for flying vehicles, lacking proactive privacy protection mechanisms for residential areas, industrial parks, and other similar spaces.

[0003] Although some drone systems support geofencing, it is mainly used for no-fly control and only restricts flight areas. It cannot dynamically adjust the sensor working mode. Moreover, existing solutions mostly involve the platform unilaterally delineating areas, without giving users the right to autonomously manage their airspace privacy.

[0004] Therefore, there is an urgent need for a user-led, safe, controllable, and real-time privacy protection mechanism that can ensure flight safety while respecting and protecting the privacy of ground users. Summary of the Invention

[0005] The purpose of this invention is to at least partially solve one of the technical problems existing in the prior art.

[0006] Therefore, one objective of this invention is to provide a flying car perception and control method based on an airborne privacy protection zone. This method meets the proactive management needs of ground users for low-altitude privacy protection, effectively prevents ground privacy leakage while ensuring the flight safety of the flying car, and provides a compliant and reliable technical foundation for the low-altitude economy.

[0007] Another objective of this invention is to provide a flying car perception and control device based on an airborne privacy protection zone.

[0008] To achieve the above-mentioned technical objectives, the technical solutions adopted in the embodiments of the present invention include: On one hand, embodiments of the present invention provide a flying car perception and control method based on an airborne privacy protection zone, comprising the following steps: Obtain the aerial privacy protection zone request data uploaded by the target user, wherein the aerial privacy protection zone request data includes the target user's real estate digital certificate and the spatial boundary information and restricted sensor list of the target aerial privacy protection zone; The target user is authenticated based on the real estate digital certificate, the spatial boundary information is spatially verified, and the access rights of the restricted sensor list are verified. Once identity verification, spatial verification, and permission verification are all successful, evidence data for the target airspace privacy protection zone is generated based on the spatial boundary information and the list of restricted sensors, and the evidence data is stored in the blockchain. Obtain the current flight trajectory of the target flying car and determine whether the current flight trajectory passes through the target airspace privacy protection zone; When the current flight path passes through the target airspace privacy protection zone, the target flying car is controlled to adjust the working mode of the on-board environmental perception sensor after entering the target airspace privacy protection zone, according to the restricted sensor list.

[0009] Furthermore, in one embodiment of the present invention, the real estate digital certificate includes the target user's real estate location information, real estate height information, real estate type information, and property owner information; the spatial boundary information includes horizontal boundary coordinates and height range; and the restricted sensor list includes several restricted sensor types and corresponding restricted time periods.

[0010] Furthermore, in one embodiment of the present invention, the steps of authenticating the target user based on the real estate digital certificate, performing spatial verification on the spatial boundary information, and performing permission verification on the restricted sensor list specifically include: Obtain the user identity information of the target user, and determine whether the property owner information is consistent with the user identity information. If they are consistent, the identity verification is deemed successful. The horizontal space redundancy is determined based on the property location information and the horizontal boundary coordinates, and the vertical space redundancy is determined based on the property height information and the height range. It is then determined whether the horizontal space redundancy and the vertical space redundancy meet the preset privacy protection space range. If they do, the space verification is deemed successful. The scope of privacy protection permissions for the target user is determined based on the real estate type information, and it is determined whether the restricted sensor type and the restricted time period meet the scope of privacy protection permissions. If they do, the permission verification is deemed successful.

[0011] Furthermore, in one embodiment of the present invention, the step of generating evidence data of the target airborne privacy protection zone based on the spatial boundary information and the restricted sensor list, and storing the evidence data in the blockchain, specifically includes: The spatial boundary information and the list of restricted sensors are encrypted and signed to obtain the evidence data. The evidence data is uploaded to the blockchain, and the corresponding creator, creation time, and hash value are recorded.

[0012] Furthermore, in one embodiment of the present invention, obtaining the current flight trajectory of the target flying car and determining whether the current flight trajectory passes through the target airspace privacy protection zone specifically includes: The current position and current flight status of the target flying car are obtained, and the current flight trajectory is predicted based on the current position and the current flight status. The three-dimensional space of the target airspace privacy protection zone is determined based on the spatial boundary information, and it is determined whether the current flight trajectory intersects with the three-dimensional space. When it is determined that the current flight trajectory intersects with the three-dimensional space, it is determined that the current flight trajectory passes through the target airspace privacy protection zone.

[0013] Furthermore, in one embodiment of the present invention, the step of controlling the target flying car to adjust the operating mode of its onboard environmental perception sensors after entering the target airspace privacy protection zone according to the restricted sensor list specifically includes: Based on the current time period and the restricted sensor list, determine the types of restricted sensors currently in use, and based on the types of restricted sensors, determine the target vehicle-mounted environmental perception sensors that need to be restricted in the target flying car. When the target flying car enters the target air privacy protection zone, the system controls the target vehicle-mounted environmental perception sensor to stop collecting environmental perception data, or controls the target vehicle-mounted environmental perception sensor to perform real-time desensitization processing on the collected environmental perception data.

[0014] Furthermore, in one embodiment of the present invention, the flying car perception and control method further includes the following steps: In response to the restricted sensor authorization request of the target flying car, determine the types of target sensors that the target flying car needs to authorize to use when passing through the target airspace privacy protection zone, and forward the restricted sensor authorization request to the target user; In response to the authorized operation of the target user, the target flying car is allowed to use the onboard environmental perception sensor corresponding to the target sensor type normally in the target air privacy protection zone.

[0015] On the other hand, embodiments of the present invention provide a flying car perception and control device based on an airborne privacy protection zone, comprising: The data upload module is used to acquire the air privacy protection zone request data uploaded by the target user. The air privacy protection zone request data includes the target user's real estate digital certificate, as well as the spatial boundary information and restricted sensor list of the target air privacy protection zone. The verification module is used to verify the identity of the target user based on the real estate digital certificate, perform spatial verification on the spatial boundary information, and perform permission verification on the list of restricted sensors. The evidence storage module is used to generate evidence storage data for the target airspace privacy protection zone based on the spatial boundary information and the list of restricted sensors when identity verification, spatial verification, and permission verification are all passed, and to store the evidence storage data in the blockchain. The privacy protection judgment module is used to obtain the current flight trajectory of the target flying car and determine whether the current flight trajectory passes through the target air privacy protection zone; The sensor control module is used to control the target flying car to adjust the working mode of the on-board environmental perception sensor after entering the target air privacy protection zone, according to the restricted sensor list, when the current flight trajectory passes through the target air privacy protection zone.

[0016] On the other hand, embodiments of the present invention provide an electronic device, including: At least one processor; At least one memory for storing at least one program; When the at least one program is executed by the at least one processor, the at least one processor implements the above-described flying car perception control method based on an airborne privacy protection zone.

[0018] On the other hand, embodiments of the present invention also provide a computer program product, including a computer program that, when executed by a processor, implements the above-described flying car perception and control method based on an airborne privacy protection zone.

[0019] The advantages and beneficial effects of the present invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention: This invention acquires aerial privacy protection zone request data uploaded by a target user. This data includes the target user's digital property certificate, spatial boundary information of the target aerial privacy protection zone, and a list of restricted sensors. The invention verifies the target user's identity based on the digital property certificate, performs spatial verification on the spatial boundary information, and verifies permissions on the restricted sensor list. When all three verifications are successful, evidence data for the target aerial privacy protection zone is generated based on the spatial boundary information and the restricted sensor list, and this evidence data is stored on the blockchain. The current flight trajectory of the target flying car is obtained, and it is determined whether the current flight trajectory crosses the target aerial privacy protection zone. If the current flight trajectory crosses the target aerial privacy protection zone, the operating mode of the onboard environmental perception sensors is adjusted according to the restricted sensor list after the target flying car enters the target aerial privacy protection zone. This invention satisfies the proactive management needs of ground users for low-altitude privacy protection, effectively preventing ground privacy leaks while ensuring the flight safety of flying cars, and providing a compliant and reliable technical foundation for the low-altitude economy.

[0026] It should be noted that in various specific embodiments of the present invention, when processing data related to user identity or characteristics, such as user information, user behavior data, user historical data, and user parking space location information, user permission or consent is obtained first. Furthermore, the collection, use, and processing of this data comply with relevant laws, regulations, and standards. In addition, when embodiments of the present invention require access to sensitive personal information of users, separate permission or consent from the user is obtained through pop-ups or redirection to a confirmation page. Only after obtaining the user's separate permission or consent is the necessary user-related data for the normal operation of the embodiments of the present invention acquired.

[0027] Reference Figure 1 This invention provides a flying car perception and control method based on an airborne privacy protection zone, specifically including the following steps: S101. Obtain the air privacy protection zone request data uploaded by the target user. The air privacy protection zone request data includes the target user's real estate digital certificate, as well as the spatial boundary information and restricted sensor list of the target air privacy protection zone. S102. Verify the identity of the target user based on the real estate digital certificate, perform spatial verification on the spatial boundary information, and verify the permissions of the restricted sensor list. S103. When identity verification, spatial verification, and permission verification are all passed, generate evidence data of the target airborne privacy protection zone based on spatial boundary information and the list of restricted sensors, and store the evidence data in the blockchain. S104. Obtain the current flight trajectory of the target flying car and determine whether the current flight trajectory passes through the target air privacy protection zone; S105. When the current flight path passes through the target airspace privacy protection zone, control the target flying car to adjust the working mode of the on-board environmental perception sensor after entering the target airspace privacy protection zone, according to the list of restricted sensors.

[0028] The embodiments of the present invention meet the proactive management needs of ground users for low-altitude privacy protection, effectively prevent ground privacy leaks while ensuring the flight safety of flying cars, and provide a compliant and reliable technical foundation for the low-altitude economy.

[0029] As an optional implementation, the real estate digital certificate includes the target user's real estate location information, real estate height information, real estate type information, and property owner information. The spatial boundary information includes horizontal boundary coordinates and height ranges. The restricted sensor list includes several restricted sensor types and corresponding restricted time periods.

[0030] Specifically, users log in to their real-name accounts via a smartphone app and bind their real estate digital certificates (through the real estate registration interface). In the app interface, users can manually draw or select the area where their real estate is located using a polygon to form horizontal boundary coordinates. They can also set the altitude range (e.g., 0–50 meters), select the types of sensors that can be restricted (e.g., visual sensors), and set the corresponding usage time limits. This allows them to obtain the request data for the airspace privacy protection zone and upload it to the low-altitude digital airspace service platform.

[0031] As a further optional implementation, the system verifies the identity of the target user, performs spatial verification of the spatial boundary information, and verifies the access rights of the restricted sensor list based on the real estate digital certificate. Specifically, this includes: S1021. Obtain the target user's identity information and determine whether the property owner information matches the user's identity information. If they match, the identity verification is deemed successful. S1022. Determine the horizontal spatial redundancy based on the real estate location information and horizontal boundary coordinates, determine the vertical spatial redundancy based on the real estate height information and height range, and determine whether the horizontal spatial redundancy and vertical spatial redundancy meet the preset privacy protection space range. If they do, the space verification is deemed successful. S1023. Determine the scope of privacy protection permissions for the target user based on the real estate type information, and determine whether the restricted sensor type and restricted time period meet the scope of privacy protection permissions. If they do, the permission verification is deemed successful.

[0032] Specifically, the Low Altitude Digital Airspace Service Platform performs compliance verification on received spatial privacy protection zone request data from three dimensions: identity, space, and permissions. Specifically: it determines whether the property owner of the real estate digital certificate is consistent with the user making the request, to prevent unauthorized users from maliciously requesting privacy protection; it determines whether the redundancy of the requested horizontal spatial coordinate range exceeding the real estate location range recorded in the real estate digital certificate is reasonable, and whether the redundancy of the requested height range exceeding the real estate height recorded in the real estate digital certificate is reasonable, to prevent users from maliciously expanding the protected area; and it determines whether the restricted sensor types and restricted time periods exceed the privacy protection permissions corresponding to the real estate type. For example, the privacy protection permissions for individual users are limited to visual sensors, while the privacy protection permissions for enterprise users may include radar.

[0033] As a further optional implementation, evidence data for the target airspace privacy protection zone is generated based on spatial boundary information and a list of restricted sensors, and the evidence data is stored on a blockchain, specifically including: S1031. Encrypt and sign the spatial boundary information and the list of restricted sensors to obtain evidence data; S1032. Upload the evidence data to the blockchain and record the corresponding creator, creation time, and hash value.

[0034] Specifically, once identity verification, spatial verification, and permission verification are all passed, the request for the airspace privacy protection zone is confirmed to have passed the compliance verification. The low-altitude digital airspace service platform encrypts and signs the spatial boundary information and the list of restricted sensors to obtain evidence data, which is then stored on the blockchain for easy traceability later.

[0035] As a further optional implementation, the current flight trajectory of the target flying car is obtained, and it is determined whether the current flight trajectory passes through the target airspace privacy protection zone, which specifically includes: S1041. Obtain the current position and current flight status of the target flying car, and predict the current flight trajectory based on the current position and current flight status; S1042. Determine the three-dimensional space of the target's airspace privacy protection zone based on the spatial boundary information, and determine whether there is an intersection between the current flight trajectory and the three-dimensional space; S1043. When it is determined that the current flight trajectory intersects with the three-dimensional space, it is determined that the current flight trajectory passes through the target's airspace privacy protection zone.

[0036] Specifically, before initiating a mission, the flying car can subscribe to the spatial boundary information and restricted sensor list of all target airspace privacy protection zones within the current flight path coverage area from the low-altitude digital airspace service platform. The onboard computing unit predicts the current flight trajectory in real time based on the current location and flight status, and determines whether there is an intersection between the current flight trajectory and the three-dimensional space corresponding to the spatial boundary information. If there is, it indicates that the flying car will pass through the target airspace privacy protection zone.

[0037] As a further optional implementation, the target flying car is controlled to adjust the operating mode of its onboard environmental perception sensors after entering the target airspace privacy protection zone, based on a restricted sensor list. This specifically includes: S1051. Determine the types of restricted sensors currently in use based on the current time period and the list of restricted sensors, and determine the target vehicle-mounted environmental perception sensors that need to be restricted in the target flying car based on the types of restricted sensors. S1052. When the target flying car enters the target air privacy protection zone, control the target vehicle's onboard environmental perception sensor to stop collecting environmental perception data, or control the target vehicle's onboard environmental perception sensor to perform real-time desensitization processing on the collected environmental perception data.

[0038] Specifically, after determining that the flying car will pass through the target airspace privacy protection zone, the type of restricted sensor is determined according to the restricted sensor list, so as to match the target vehicle-mounted environmental perception sensor that needs to be restricted on the flying car; taking the visual sensor as an example, when the target flying car enters the target airspace privacy protection zone, the visual sensor is controlled to be turned off or the hardware-level image blurring module is activated to perform real-time desensitization processing on the environmental perception image it collects. At the same time, the main source of perception of the target flying car is switched to radar.

[0039] As an optional implementation, the flying car perception control method further includes the following steps: S106. In response to the restricted sensor authorization request from the target flying car, determine the types of target sensors that need to be authorized for use when the target flying car passes through the target air privacy protection zone, and forward the restricted sensor authorization request to the target user; S107. In response to the authorized operation of the target user, allow the target flying car to use the onboard environmental perception sensor corresponding to the target sensor type normally in the target air privacy protection zone.

[0040] Specifically, if the target flying car must use visual sensors (such as for emergency landing), an authorization request can be sent to the user through the low-altitude digital airspace service platform. After the user confirms remotely, the visual sensors can be used normally in the target airspace privacy protection zone. At the same time, all image processing is completed on the vehicle end, and the original frames do not leave the vehicle.

[0041] In some optional embodiments, users can view their "recent access history" in the app, including the flying car ID, time, and whether privacy protection was triggered.

[0042] Based on the embodiments of the present invention, individual users can define a three-dimensional privacy zone above their residences and set perception restrictions, while enterprise users can define a three-dimensional privacy zone above their industrial parks and set perception restrictions. After verification by the low-altitude digital airspace service platform, the data is uploaded to the blockchain. When the flying car enters the corresponding area, it automatically switches to a privacy perception mode, such as turning off the camera or enabling non-optical sensors, and completes data anonymization at the edge to avoid infringing on the privacy of individual and enterprise users.

[0043] The method steps of the embodiments of the present invention have been described above. It can be understood that the embodiments of the present invention meet the proactive management needs of ground users for low-altitude privacy protection, effectively preventing ground privacy leaks while ensuring the flight safety of flying cars, and providing a compliant and reliable technical foundation for the low-altitude economy.
